Peristaltic Motion of a Johnson-segalman Fluid in a Planar Channel
This paper is devoted to the study of the two-dimensional flow of a Johnson-Segalman fluid in a planar channel having walls that are transversely displaced by an infinite, harmonic travelling wave of large wavelength. Both analytical and numerical solutions are presented. The analysis for the analytical solution is carried out for small Weissenberg numbers. (A Weissenberg number is the ratio of...
متن کاملPeristaltic Motion of Johnson-Segalman Fluid in a Curved Channel with Slip Conditions
Slip effects on the peristaltic transport of Johnson-Segalman fluid through a curved channel have been addressed. The influence of wall properties is also analyzed. Long wavelength and low Reynolds number assumptions have been utilized in the mathematical formulation of the problem. The equations so formed have been solved numerically by shooting method through computational software Mathematic...
متن کاملPeristaltic transport of a Johnson-Segalman fluid in an asymmetric channel
This paper deals with peristaltic flow of a Johnson–Segalman fluid in an asymmetric channel under long-wavelength and lowReynolds number considerations. The channel asymmetry is caused due to the peristaltic wave train on the walls having different amplitudes and phase. A series solution for small Weissenberg number is obtained for the stream function, axial velocity, axial pressure gradient an...
متن کاملPeristaltic motion of a Carreau fluid in an asymmetric channel
Peristaltic transport of a fluid in channels has been a subject of great interest for the last four decades. Such interest is motivated by several applications of peristaltic flows in engineering and industry. In animals and human bodies, the physiological fluids pumped by the muscular oscillations which correspond to peristaltic activity. In particular, the flow of blood through arteries and v...
متن کاملPeristaltic Viscoelastic Fluid Motion in a Tube
Peristaltic motion of viscoelastic incompressible fluid in an axisymmetric tube with a sinusoidal wave is studied theoretically in the case that the radius of the tube is small relative to the wavelength. Oldroyd flow has been considered in this study and the problem is formulated and analyzed using a perturbation expansion in terms of the variation of the wave number. This analysis can model t...
